Diborane can be made with the following unbalanced reaction: NaBH_(4(s))+I_(2(s))→B_2 H_(6(g))+NaI_((s))+ H_(2(g))

If 1.203g of NaBH4 are reacted with 7.050g of iodine, what is the theoretical yield of diborane in grams?
If you isolate 0.295g of diborane, what is your percent yield?

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.  

a) the particles of the chair are strongly held together.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
